BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Mar. 7, 191 6.

Application filed April 24, 1915. Serial No. 23,599.

To all whom it may concern:

Be it known that I, SOMA Hnnzoo, acitiland Park, Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Bottle-Closures, of which the following is a specification.

This invention relates to a sealing'attachment for bottles, jugs, ars and similar vessels, and the object thereof is to provide an attachment which will automatically seal the vessel when it is in an'upright position and will permit liquid to flow therefrom when in inverted position.

It is another object of this invention to provide an attachment for sealing vessels which may be placed in the neck of the vessel, so that liquid cannot be poured into the vessel without breaking the neck thereof. It is a further object to constructa sealing attachment of few parts and which will not require springs or complicated apparatus to operate it. 7

I attain these objects by means of the embodiment of my invention illustrated in the accompanying drawing, in which:

Figure 1 is a plan view of the neck of a bottle with my improved sealing attachment inserted therein, the neck of the bottle being in section. Fig. 2 is a section of the sealing attachment and bottle neck, showing the parts of the sealing attachment in position for the outflow of liquid. Fig. 3 is a horizontal section on the line 33 of Fig. 1. Fig. 4 is a horizontal section on the line 1-4 of Fig. 3. I

More specifically, 5 indicates the neck of a bottle of the usual type whichis provided with an enlarged portion 6 at the mouth. The bore 7 of the neck is enlarged near the mouth as indicated at 8 and a shoulder 9 formed between bores 7 and 8. The shoulder 9 serves as a seat for a reciprocating plug 10. l

The reciprocating plug 10 comprises a hollow cylindrical body 11 with a plurality of apertures 12 in the wall thereof. The lower end of plug 10 is open to the neck of the bottle and closed at the top by a disk 13 of greater diameter than the bore 7 so that when the plug'lO is in its lower position, the disk 11 will seat upon the shoulder 9 forming a closure for the neck of the bottle and hermetically sealing the same.

In the upper portion of'the bore 8 and ad- 7 air,

jacent the edgeof themouth, an open cylindrical plug 1 1 is inserted and secured to the mouth 6 by a suitable cement. The exterior diameter of the plug 1 1 is reduced at the lower end to form a channel 15. The plug 141 is formed on its lower edge with teeth so that when disk 13 abuts the edge of the plug 14, an outlet for liquid is provided for liquid, passing around the edge of disk 11 and through the opening 17 between the teeth.

The plugs 10 and 1 1 are preferably constructed of glass, but may be formed of rubber, caoutchouc, magnesia, metals, such as lead which are not eflected by. most liquids. My sealing attachment may be constructed with a neck 5'which forms a stopper to be placed over the neck of the bottle.

In use, when the bottle is in upright position, the plug 10 drops by its own weight so that disk 13 rests upon seat 9, thereby closing the neck of the bottle and preventing the entrance of air or liquids into the bottle. If it is desired to pour liquid from the bottle, the bottle is inverted, the plug 10 moving toward the mouth, the disk 13 being supported'by the ends of the teeth 15, thereby uncovering the ports 12 and permitting liquid to flow through the body 10, ports 12, around the edge of disk 13 and through channel 15 openings 17, between teeth 16 and thence out of the mouth of the bottle.

It is obvious that my sealing attachment may be applied to any bottle and that the seat 9 may be formed when the bottle is blown, thereby requiring no expensive operation to be performed upon the bottle after it is blown or in any way disturbing the same. or marring its appearance. The plug 10 may be dropped therein and the plug 11 cemented in place.

In the shipment of bottles provided with my device, no cork is required since the plug 10 seals the bottle and prevents entrance of dirt or liquids. In using the bottle it is not necessary to remove a cork 0r stopper.

My sealing attachment is especially suited for liquids which tend to explode the bottle in which they are contained, as the reciprocating disk will be lifted from itsseat on an increase or pressure from within, thereby relieving the pressure in the bottle.

What I claim is:
